[Ryo Kanbayashi <kanbayashi@xxxxxxxxxxxxxxxxxxxxx>]

Hi all.

I'm now try to read and write puseud physical memory of domU from Dom0
with xenaccess(this is using libxc).
#http://xenaccess.sourceforge.net/

With xenaccess, I'm succeeded read and writing almost of the memory. But
It fail when I try to access head 1M region and some bit regions.
To be precise, xc_map_foreign_range() of libxc returns error code.
** <javascript:goWordLink("to")>

What's allocated on head 1M region of domU?
#and , Can I get a document about memory allocation of dom0 and DomU
somewhere?

regards.
